Question 2042
A few other ways to solve this:

The quickest way, if you know a value, and the percent of the whole it represents, you can do the following:

# of women: 12 * 1/3 = 4 women

We know that in the end, when the team has all it's members, 4 women will equal 20% of the team.   

You can divide 4 by .20 to determine the total number of members on the team.   This comes from knowing that having a portion of a whole, and knowing what percent it represents of the whole, you can divide through to get the total number.

4 / .20 = 20

20 total team mates - 4 women, minus the 8 original men from (12 * 2/3 = 8) = 

20 - 4 - 8 = 8 men (final answer)

You can verify this by seeing that 20 (the total number of players) * .20 (the percent of the team that is women) = 4.

Another way to do this is:



This comes from knowing that in the end, if the women are 20% of the team, then the men are 80%, so we know that

(number of men) / (entire team) = .80

number of men = 8 + x
total team = 12 + x

(8 + x) / (12 + x) = .80
